About Jam Paper #11 Business Commercial Envelopes 4 1/2 x 10 3/8
77% praised the high-quality paper, but 23% found it too thin
I buy JAM business stationary supplies because I am impressed with the appearance and texture of the paper used in their commercial business envelopes.
I noticed that the paper seemed thicker and the window did not melt. This could be a positive sentiment towards the paper quality of business-mailing-envelopes.

The envelopes were flimsy, wilted, and most of them were stuck together, making them entirely unusable.
I noticed that the envelopes I received were not as heavy as the pricey 28 lb non-window envelopes I had purchased in a stationery store. The envelopes I received were not as heavy as the pricey 28 lb non-window envelopes I had purchased in a stationery store.
80% loved the crisp printing quality, while 20% experienced smudging
To format my self-designed/printed invoices correctly, I needed to know the size of the window opening and the measurement of the window from the edges of the envelope.
I have complained that the quality of the envelopes has changed. The window melts and shrinks causing the entire envelope to warp, which creates problems with printing on it using a laser printer.
72% appreciated the secure seal, though 28% experienced leaks
Most of the envelopes were unusable as the glue on the flaps caused them to stick together.
The new order feels rougher, making it seem cheaper and less professional.
80% liked the added security features
I bought these envelopes to send out self-printed invoices, which shows my concern for security features of business-mailing-envelopes.
93% liked the perfect size and fit, while 7% found it too snug
These #11 envelopes are perfect for forwarding any #10 envelopes.
I am dissatisfied with the envelopes as they are of poor quality and not fit for use.
81% praised the envelope's tear resistance, but 19% experienced tears
I have purchased JAM paper products before and from my experience, the company manufactures decent quality paper products.
I have experienced issues with the envelope warping and causing the printer to jam multiple times due to the material used for the window melting and shrinking.
